Abstract
The invention provides a time-sequence control method for pipe replacement of an automatic bobbin winder. The time-sequence control method is characterized in that when a cop sucker descends from the starting position to grab yarns and a yarn feeding sensor judges that no yarn exists, the cop sucker continuously ascends to the working position of a twist connector, a yarn pre-clearer and a tension bowl are opened, and then the yarns are cut off by scissors; when the cop sucker ascends continuously to be matched with a twist connector support and is opened, a section of yarns cut off is sucked into a negative-pressure pipeline by negative pressure, and then the cop sucker descends to the starting position, pipe replacement is carried out by a single-spindle pipe replacer, after the pipe replacement, the cop sucker returns to the starting position and prepares the next twist connection circulation. Two or more yarns are effectively avoided from being grabbed by the cop sucker, and twist connection failure caused by the fact that multiple yarns are fed into the twist connector by the cop sucker is avoided, production efficiency is improved, and waste of the yarns is reduced. Further, the control method is simple and convenient, and no equipment needs to be modified.
Description
Technical field
The invention belongs to technical field of textile machine, relate to the improvement of automatic winder control method, is a kind of automatic winder replace tubes sequential control method specifically.
Background technology
On ESPERO automatic winder list ingot, be designed with lower scissors structure, grabbed yarn if lower yarn sensor judges cop suction nozzle, lower scissors is failure to actuate, and the circulation of proceeding to splice; If lower yarn sensor judges when cop suction nozzle does not grab yarn, scissor action once, is cut off because of lower yarn sensor and is judged the yarn being captured by cop suction nozzle by accident, avoids cop suction nozzle to grab the possibility of two or threads simultaneously.
At present, the SPERO releasing on market and SMARO automatic winder do not have lower scissors structure, when cop suction nozzle grabs yarn, and lower yarn sensor is mistaken for while thering is no yarn, single ingot will carry out replace tubes action, causes cop suction nozzle to catch two or threads, causes the circulation of splicing unsuccessful, affect production efficiency, waste yarn; Or yarn one end is captured by cop suction nozzle, the spool of being chosen is followed blank pipe conveying belt and is moved ahead, and causes yarn to be wrapped in the phenomenon on fuselage.
Summary of the invention
The present invention is directed to the problems referred to above that prior art exists, a kind of automatic winder replace tubes sequential control method is provided, effectively prevention cop suction nozzle grabs the phenomenon of two or threads simultaneously, avoid, because of cop suction nozzle, two or threads feeding splicer is caused to the unsuccessful problem of splicing, improve production efficiency, reduced yarn waste.And control method is easy, without reforming equipment.
The object of the invention is to be achieved through the following technical solutions:
A kind of automatic winder replace tubes sequential control method, comprise controller, cop suction nozzle, cop suction nozzle transmission device, lower yarn sensor, splicer, splicer support, pre-yarn clearer, tension pulley, scissors, negative-pressure pipeline, Dan Ding replace tubes mechanism, signal and up, the descending action of control cop suction nozzle that described controller sends for receiving lower yarn sensor, it is characterized in that, replace tubes sequential control method step is:
When cop suction nozzle grabs after yarn by reference position is descending, and lower yarn sensor is judged as while thering is no yarn, and cop suction nozzle continues up, goes upward to the position of splicer work, and pre-yarn clearer and tension pulley are opened, and now scissor action, cuts off yarn; Cop suction nozzle continues up, and with splicer support assorted, cop suction nozzle is opened, and one section of yarn cutting off relies on negative pressure to be sucked into negative-pressure pipeline; Then, cop suction nozzle comes downwards to original position, and by Dan Ding replace tubes, mechanism carries out replace tubes action, and after replace tubes finishes, cop suction nozzle comes back to original position, prepares to splice circulation next time.
Improvement to technique scheme: described cop suction nozzle is 10 °-20 ° by reference position to the rotational angle that grabs yarn; The rotational angle that cop suction nozzle goes upward to splicer control position by the position that grabs yarn is 120 °-140 °; It is 5 °-15 ° that cop suction nozzle goes upward to by splicer control position the rotational angle that splicer support makes cop suction nozzle open position.
Advantage of the present invention and good effect are:
The present invention is directed to the misoperation problem that does not have the automatic winder of lower scissors to run in doff process, a kind of automatic winder replace tubes sequential control system is provided, effectively prevent cop suction nozzle to grab the phenomenon of two or threads simultaneously, avoided causing because threads is fed splicer by cop suction nozzle the unsuccessful problem of splicing.Improve production efficiency, reduced yarn waste.
Brief description of the drawings
Fig. 1 is the principle of work schematic diagram of a kind of automatic winder replace tubes of the present invention sequential control method;
Fig. 2 is the FB(flow block) of a kind of automatic winder replace tubes of the present invention timing method.
Detailed description of the invention
Referring to Fig. 1, Fig. 2, the embodiment of a kind of automatic winder replace tubes of the present invention sequential control method,
Comprise controller, cop suction nozzle 2, cop suction nozzle transmission device, lower yarn sensor 1, splicer, splicer support 3, pre-yarn clearer, tension pulley, scissors, negative-pressure pipeline, Dan Ding replace tubes mechanism, signal and 2 up, the descending actions of control cop suction nozzle that described controller sends for receiving lower yarn sensor, replace tubes sequential control method step is:
When cop suction nozzle 2 is come downwards to and grabbed yarn position A and grab after yarn by reference position D, and lower yarn sensor 1 is judged as while thering is no yarn, and cop suction nozzle 2 continues up, go upward to the position B of splicer work, pre-yarn clearer and tension pulley are opened, and now scissor action, cuts off yarn; Cop suction nozzle 2 continues to go upward to position C, coordinates with splicer support 3, and cop suction nozzle 2 is opened, and one section of yarn cutting off relies on negative pressure to be sucked into negative-pressure pipeline; Then, cop suction nozzle 2 comes downwards to reference position D place, and by Dan Ding replace tubes, mechanism carries out replace tubes action; After replace tubes finishes, cop suction nozzle 2 comes back to reference position D place, prepares to splice circulation next time.
In above-mentioned control method: cop suction nozzle 2 by reference position D to the rotational angle that grabs yarn position A be 10 °-20 °; The rotational angle that cop suction nozzle 2 goes upward to splicer control position B by the position A that grabs yarn is 120 °-140 °; It is 5 °-15 ° that cop suction nozzle 2 goes upward to by splicer control position B the rotational angle that splicer support 3 makes cop suction nozzle 2 open position C.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, variation, remodeling, interpolation or the replacement done, also should belong to protection scope of the present invention.
